Back for another trip! This time I engrave some plastic stemless wine glasses I picked up for cheap. Settings and results (which were amazing once dialed in) below!

You may have noticed that for all of these rotary jobs I have been preferring the Blue Lens. There is actually a reason (or two) for that. First and foremost, it allows me a little play when focusing the laser. Since the beam is the most constant with this lens, you can tolerate (read: ignore) minor imperfections and shifts in the profile of the glass. This helped a lot for this glass, because it was rather curved. Another reason is that it gets the lens head a longer clearance from the machinery. Always check your clearance (even past what you think you need) before you cut. Always.

Take 2 on the pint glasses. I made 2 more: one for Julie and one for Devon. Still on Cantaloupe (because it’s the one traditionally used with the rotary encoder. Pay attention because the settings are slightly different, and we like them slightly better:

Note: The laser is .25″ out of focus (longer) – We think this is what caused the smoother feel to the etched portion.
